Cognitive entity reference recognition

ABSTRACT

Methods, computer program products, and systems are presented. The methods include, for instance: monitoring one or more message of the conversation between multiple users for an entity reference; detecting the entity reference in a message in the conversation. An entity reference list stores previously established alternate name referring to a user in the conversation. By analyzing the message and following messages in the conversation for relevance of and sentiment to the entity reference, the entity reference is evaluated and if acceptable, the entity reference list is updated with the entity reference as a new alternate name to identify the user in subsequent messages.

CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation of U.S. application Ser. No.15/434,279, filed Feb. 16, 2017, entitled “Cognitive Entity ReferenceRecognition”, which is incorporated by reference herein in its entirety.

TECHNICAL FIELD

The present disclosure relates to cognitive computing technology, andmore particularly to methods, computer program products, and systems forrecognizing names referring to a certain entity and assistingparticipants of a conversation with the name-entity associations.

BACKGROUND

In conventional group messenger applications, participants may notrecognize alternate names referring to a certain user as some users mayuse one alternate name and other users may use another alternate name.All participants in a group conversation may not be aware of allnicknames for other participants, which may be made up during theconversation. Accordingly, users need to exchange messages only toidentify which name refers to whom during the group conversation.

SUMMARY

The shortcomings of the prior art are overcome, and additionaladvantages are provided, through the provision, in one aspect, of amethod. The method for recognizing a reference to an entity from aconversation includes, for example: monitoring, by one or moreprocessor, one or more message of the conversation between two or moreusers for an entity reference, wherein the two or more users haverespective user profiles including respective user names; detecting theentity reference in a message of the one or more message from themonitoring, the entity reference being not present in an entityreference list, wherein the entity reference list includes zero or morealternate name referring to a user of the two or more users, wherein analternate name is distinctive from the respective user names; analyzingthe message and following messages in the conversation for relevance ofthe entity reference and sentiment associated with the entity reference;determining that the entity reference is appropriate for later use basedon the analyzing and respective thresholds for relevance and sentiment;and updating the entity reference list with the entity reference as anew alternate name for the user such that the user may be identified byuse of the new alternate name in subsequent messages.

Additional features are realized through the techniques set forthherein. Other embodiments and aspects, including but not limited tocomputer program product and system, are described in detail herein andare considered a part of the claimed invention.

DETAILED DESCRIPTION

FIG. 1 depicts a system 100 for cognitive entity reference recognition,in accordance with one or more embodiments set forth herein.

The system 100 includes a user 101, a user device 110, and one or moremessage in a conversation 105. The conversation 105 is conducted over atelecommunication network amongst one or more group of users, by use ofcompatible messaging application programs running on respective userdevices. The telecommunication network and the messaging applicationprograms are not shown in the system 100, as the conversation 105 maytake place by use of conventional telecommunication environments andmessaging tools not within the scope of this specification. The userdevice 110 runs a cognitive entity reference recognition engine 120 thatdynamically recognizes references to users/groups from the conversation105 and presents an entity reference adjusted message 199 to the user101 for a corresponding message 107 from the one or more message in theconversation 105.

The cognitive entity reference recognition engine 120 includes aresponse catalogue 130, an entity reference list 140, a query generator150, a response analyzer 160, and a cognitive entity reference listingprocess 170. The cognitive entity reference recognition engine 120 mayemploy various external service utilities including a machine learningprocess 181, a content analytics process 183, a natural languageclassification process 185, and a sentiment analysis process 187. Themachine learning process 181 may be utilized to create appropriateresponses to a preceding message, as trained by actual conversationmessages. The content analytics process 183 may be utilized to analyzetopics of the conversations, etc. The natural language classificationprocess 185 may be used to classify the messages as well as componentsof the messages as employed by the query generator 150. The sentimentanalysis process 187 may be used to assess sentiments associated withentity references by the response analyzer 160, as used by the cognitiveentity reference listing process 170 to evaluate the entity references.

The response catalogue 130 stores messages that may be providedresponsive to a preceding message in conversations. The responsecatalogue 130 may be created by use of, but not limited to, pastmessages and conversations, various external service utilities includingthe machine learning process 181 and the content analytics process 183,etc. In certain embodiments of the present invention, a message of theresponse catalogues 130 may be associated with other responses suitablefor the preceding message, respective sentiment associated with eachresponse, the context of the patterns stored in the response catalogue130, etc.

The entity reference list 140 stores one or more entity names that maybe used in displaying the entity names in messages for the user 101. Auser may have a registered user name, a chat name configured for eachconversation thread, or one nickname used for all conversations, etc.,as updated by the cognitive entity reference listing process 170. Theentity reference list 140 stores the one or more entity names anddisplay the most relevant name for the participants of the conversation.An exemplary message displays for respective participants in a sameconversation is presented in FIG. 3B and corresponding description.

The query generator 150 creates a query upon detecting a new entityreference appearing in the message 107, which is not stored in theentity reference list 140. In this specification, the term “classifier”refers to a group of words that is likely to contain a name for aperson. For example, in a message to a user named “Robert” stating “Hi,Bob, how are you doing?”, “Hi/Bob/you/?” is a classifier that includes agreeting “Hi”, followed by an unknown term of address “Bob”, andfollowed by the second person pronoun “you”, in an interrogativesentence marked by a question mark (?). The classifier “Hi/Bob/you/?”signifies that the unknown term of address “Bob” is likely to indicatethe user “Robert” to whom the message is being addressed. Also in thisspecification, the term “query” refers to an inquiry as to if thealternate reference appearing in the classifier refers to the entity,and includes the classifier, the user, and an alternate reference to theuser. In the previous example, the query (Classifier, User, AltName) maybe instantiated as (Classifier=hi/Bob/you/?, User=Robert, AltName=Bob),inquiring if “Bob” refers to the user “Robert” by user of the classifier“hi . . . you . . . ?”, to whom the message is being addressed. Thequery generator 150 may utilize one or more external service utilities,including the content analytics process 183 and the natural languageclassifier 185, etc.

The response analyzer 160 analyzes contexts of conversations anddetermines whether or not the new entity reference is proper andrelevant within the context of the conversation. Further the responseanalyzer 160 may utilize external service utilities such as thesentiment analysis process 187 to assess sentiment associated with theresponse in using the new entity reference.

The cognitive entity reference listing process 170 passively monitorsmessages of the conversation 105, detects a new entity reference fromthe messages, and processes the entity reference by coordinating andcontrolling operations of the query generator 150 and the responseanalyzer 160, and by utilizing and updating data stored in the responsecatalogue 130 and the entity reference list 140. Detailed process of thecognitive entity reference listing process 170 is presented in FIG. 2and corresponding description.

While using messaging services for groups, participants in a groupconversation may use various names to refer to one user. The groupconversation is ordinarily conducted by use of group chat applicationsand/or group text messengers. Over time, the names may evolve to othernames and if the participants do not follow the group conversationclosely, it would be very difficult for such infrequent participants tounderstand who is talking about whom. Similarly, wherein one user iscalled by many names, participants of the group conversation may notunderstand who is addressed by what name, may forget some names whileremembering others, etc., and the group conversation may be frequentlyinterrupted due to the inconsistency in the terms of address amongst theparticipants. Conventional messaging applications uses rudimentarymanual setting of one or more chat name, which does not reflect theterms of address for respective users in the ongoing conversation.

Certain embodiments of the present invention dynamically recognizesterms of address associated with entities from conversation messages asentity references based on relevance and semantics of the language,analyzes the sentiment accompanying the entity references, and registersthe entity references that are positively accepted for future usage.Further, based on the characterization of the groups, certain alternatenames may be further evaluated for the appropriateness. For example, fora group conversation amongst high school friends, rather informalnicknames for one user may be evaluated as acceptable, while the sameinformal nicknames for the same user may be evaluated as inappropriatefor another group conversation amongst work colleagues.

FIG. 2 depicts a flowchart performed by the cognitive entity referencelisting process 170 of FIG. 1, in accordance with one or moreembodiments set forth herein.

Each of blocks 210 through 250 is a predefined process, in whichmultiple operations may be performed to achieve respectivefunctionalities. In preparation of running the cognitive entityreference listing process 170, a user profile including user nameinformation had been configured either manually by a user orautomatically by the cognitive entity reference recognition engine 120for each user.

In block 210, the cognitive entity reference listing process 170monitors messages of a conversation in real-time and detects a newreference to an entity and use contexts of the new reference in amessage by analyzing individual messages of the conversation. Asentities in the conversation are people and people refer to other peopleby respective names, the references to entities may be names ofparticipants in the conversation, and may be detected by naturallanguage classification on the subject word, sentence structure analysisas well as part of speech analysis, including but not limited topositions relative to, greetings, punctuations, beginning and/or end ofa sentence, etc. If one of the participants in the conversation refersto another participant by using an alternate name other than what isalready known to other participants, as stored in the entity referencelist 140, the cognitive entity reference listing process 170 may detectsuch alternate name. A participant may belong to multiple conversationgroup based on the relationships amongst members of each conversationgroup, in which the participant may be referred to by distinctive names.For example, a user may have a respective conversation thread withfamily members who call the user “Eddy”, with colleagues who call theuser “Ed”, and with bowling teammates who call the user “Little Ed”,etc. The cognitive entity reference listing process 170 detects thealternate reference as a new reference if the alternate reference is notdiscovered in the entity reference list 140, in which the new referencewould be stored, as resulting from block 250. Exemplary usage ofmultiple alternate references to one entity is presented in FIG. 3B andcorresponding description. Then the cognitive entity reference listingprocess 170 proceeds with block 220.

In block 220, the cognitive entity reference listing process 170 createsa query for an alternative name detected in block 210 and initiatesanalysis of subsequent messages in the conversation. The query for thealternate name may include a classifier and additional attributes,including the alternate name and/or usage context of the alternate name.Then the cognitive entity reference listing process 170 proceeds withblock 230.

In certain embodiment of the present invention, the cognitive entityreference listing process 170 may create the query based on the contextof messages in the conversation, even the alternate name had not beendetected in block 210 because the alternate name was not a typicalentity reference such as a proper noun and/or other candidatewords/phrases. In certain embodiment of the present invention, theclassifier of the query may be obtained by an external service utilitysuch as a natural language classifier. For example, a query having aclassifier “hey/Rob/you/?” and AltName “Rob” may be created based on amessage from Nathan to Robert stating “Hey, Rob, can you call me?” for“User=Robert”. In the same example, the query may further include usagecontexts representing circumstances in which the alternative name “Rob”is used for the user “Robert”, such as a specific group of participantsin a conversation, a particular user who used a specific alternativename, etc. Accordingly, the query may further include“Attribute:Group=ABC High” as Robert and Nathan are in a group chattitled ABC High, “Attribute:UsedBy=Nathan” as Nathan used the AltName“Rob”, and/or additional alternative name and usage contexts that hadbeen previously detected as an alternative reference to the user Robertand stored in the entity reference list.

In block 230, the cognitive entity reference listing process 170evaluates the entity reference detected in block 210 based on thesubsequent message in the conversation, as analyzed from block 220. Thenthe cognitive entity reference listing process 170 proceeds with block240.

In certain embodiments of the present invention, the entity referencemay be evaluated for relevance, sentiment, confidence, and combinationsthereof, wherein the relevance indicates how accurately the entityreference designates an entity participating in the conversation andconversely may be measured by how accurately the user responds to themessage in subsequent messages in the conversation. In the sameembodiment of the present invention, the sentiment indicates howpositively or negatively the entity reference is perceived by the entitybeing designated and/or other participants of the conversation, whichmay be measured by examining how positively or negatively the userresponds to the entity reference in the following messages. In the sameembodiment of the present invention, the confidence indicates howconfident the participants may be on referring the entity by the entityreference based on the number of comparable references. For example, thecognitive entity reference listing process 170 may assign a very highlevel of confidence on an “AltName=Ed”, or “AltName=Eddy” for“User=Edward”, but would assign a very low level of confidence on an“AltName=Jack” for “User=Edward”, based on the number of entityreferences in historical data for past conversations. In certainembodiments of the present invention, the cognitive entity referencelisting process 170 evaluates the entity reference in two stages, firstby relevance and next by sentiment, such that the entity reference maybe reasonably accurate in referring to the entity and the reference isreusable as being positively perceived. Exemplary entity referenceevaluation is described in FIG. 3A and corresponding description.

In block 240, the cognitive entity reference listing process 170determines whether or not the new entity reference detected from block210 is acceptable such that the new entity reference may be reused torefer to the entity in later messages of the same conversation thread aswell as other conversations. In certain embodiments of the presentinvention, the cognitive entity reference listing process 170 maydetermine the acceptability of the new entity reference by use of, interalia, a respective range of applicable metric values, respectivethresholds for cut-off for each applicable metrics, etc., depending onthe methods of evaluation from block 230. For example, if the relevanceof the entity reference is quantified as a score during evaluation ofblock 230, then the acceptability test may be a range of relevancescores. Also in the same example, the relevance of the entity referencemay be classified in one of three levels including low, medium, andhigh, indicating medium to high level of relevance to be acceptable. Foranother example, if the sentiment of the entity reference is evaluatedas one of three categories including positive, neutral, and negative,then acceptability test may be a cut-off for the entity referenceassociated with a negative sentiment, and the entity referenceassociated with either positive or neutral sentiment may be acceptable.Sentiments may be evaluated for the new entity reference on the messagewherein the new entity reference first appeared, subsequent messagesresponding to the new entity reference, and/or any comment on the newentity reference within the group conversation, etc. If the cognitiveentity reference listing process 170 determines that the new entityreference is acceptable, then the cognitive entity reference listingprocess 170 proceeds with block 250. If the cognitive entity referencelisting process 170 determines that the new entity reference is notacceptable, then the cognitive entity reference listing process 170concludes processing the new entity reference detected in block 210.

In block 250, the cognitive entity reference listing process 170 updatesthe entity reference list 140 with the new entity reference such thatthe new entity reference may be reused to identify the entity as analternate name, as established in blocks 220 through 240. Exemplaryusage of multiple alternate references to one entity is presented inFIG. 3B and corresponding description. The user 101 may manually removeor edit entity references in the entity reference list 140, and/or mayturn on and turn off the cognitive entity reference recognition engine120 on the user device 110. Also the alternate references may bedistinctive for respective groups and/or conversations for the sameuser, and based on analyzing participants and known entity references ofthe participants, entity references may be transferred from other entityreference lists of the participants. In certain embodiments of thepresent invention, updated entity reference list 140 may be synchronizedwith other entity reference lists on user devices of respectiveparticipants of the same group conversation. Then the cognitive entityreference listing process 170 concludes processing the new entityreference detected in block 210. The cognitive entity reference listingprocess 170 iterates blocks 210 through 250 as a unit while passivelymonitoring messages in conversations.

FIGS. 3A and 3B depict exemplary conversation messages as processed bythe cognitive entity reference listing process 170, in accordance withone or more embodiments set forth herein.

Prior to running the cognitive entity reference recognition engine 120application program, both Robert and Nathan had filled out respectiveuser name information in the respective user profile for the cognitiveentity reference recognition engine 120 application program running onthe respective user devices. Both users may have configured therespective entity reference lists that catalogues nicknames for peoplein the conversations. The cognitive reference recognition engine 120application program may run as an add-on and/or plug-in program forconventional messaging applications.

In the conversation of 301 and 302 of FIG. 3A, Robert and Nathan areparticipating in a group chat for Group A of close friends. In message301, Nathan asks if Robert wants to join them in plans for the evening.Boldfaced “Rob” in message 301 indicates a nickname of Robert used inthe group chat A. If the cognitive entity reference listing process 170detects “Rob” in message 301 for the first time, the cognitive entityreference listing process 170 generates a query if “Rob” is a usablenickname for the user “Robert” and proceeds with analyzing message 302to see how the alternate name “Rob” is responded. In message 302, thecognitive entity reference listing process 170 extracts “Hey”, “Ya”, and“I”, and evaluates the alternate name “Rob” as relevant to “Robert” aswell as associated with an positive/neutral sentiment based on“Hey/Ya/I” in a declarative statement, which properly responds tomessage 301 as if the registered user name “Robert” has been used.Accordingly, the cognitive entity reference listing process 170 updatesthe entity reference list with the nickname “Attribute:AltName=Rob” for“User=Robert” as “Attribute: UsedBy=Nathan” or “Attribute:UsedBy=GroupA”.

Further in the conversation of 311 through 313 of FIG. 3A, Robert andNathan are exchanging messages, following the conversation of 301 and302. In message 311, Nathan addresses Robert with a nickname “Rob”,which had been previously registered as above. In message 312, Robertuses a new term of address “Natedog” in responding to message 311 aswell as asking another question “Hey/Natedog/yes; Are/you/?”. As inanalyzing message 302, the cognitive entity reference listing process170 detects “Natedog”, generates a query if “Natedog” is a usablenickname for the user “Nathan” and proceeds with analyzing message 313to see how the new alternate name “Natedog” is responded. In message313, the cognitive entity reference listing process 170 extracts “Yes”,“you”, and “great”, and evaluates the alternate name “Natedog” asrelevant to “Nathan” as well as associated with an positive/neutralsentiment based on “Yes/great” used in a declarative statement, whichproperly responds to message 312 as if the registered user name “Nathan”has been used. Accordingly, the cognitive entity reference listingprocess 170 updates the entity reference list with the nickname“Attribute:AltName=Natedog” for “User=Nathan” as “Attribute:UsedBy=Robert”. Further, the cognitive entity reference listing process170 may be configured to permit all participants in the same group chatto use the nickname in the entity reference list without furtherevaluation, as the group chat members may share similar recognition andsentiment for the nickname as other participants.

In another conversation having message 320 of FIG. 3B, Robert, Mark, andJane are exchanging messages, in another group chat for a book club.Jane and Robert are college friends and, because Robert goes by “Rob”amongst the college friends, Jane calls Robert Rob. Mark and Robert arework colleagues, and, because Robert goes by Bob at work, Mark callsRobert Bob. Both nicknames “Rob” and “Bob” are stored in the entityreference list for “Robert” in respective user devices for Jane andMark. In message 320, Jane is asking Robert a question by calling Robertby one of the nicknames “Rob”. On the user device of Jane, message 320Jwith the nickname “Rob” is displayed as Jane used. On the user device ofRobert, message 320R with the nickname “Rob” is displayed as Jane usedsuch that Robert would know that Jane asked the question. On the userdevice of Mark, message 320M with the nickname “Bob” is displayedbecause Mark is not familiar with Robert going by “Rob” and Mark may beconfused with the nickname “Rob”.

Certain embodiments of the present invention may offer various technicalcomputing advantages in assisting users, including automated cognitiveentity reference detection and customized replacement for respectiveusers in group conversation messages. Multiple terms of address for auser in a group conversation may be stored in an entity reference liston respective user devices and synchronized for participants of the samegroup conversation such that the recorded entity references would berecognized as nicknames for the user later. A new entity reference wouldbe detected by content analytics and natural language classification ofwords and/or messages forming a context for the entity reference. Thenew entity reference is evaluated by relevance, confidence, andsentiment associated with the entity reference such that only a relevantand associated with a positive sentiment would be accepted for repeatedusage. Certain embodiments of the present invention improves efficiencyand accuracy in identifying one user by numerous alternate names, aswell as presents individualized display of alternate names pursuant tofamiliarity of individual users for respective names. Certainembodiments of the present invention assists participants of a groupconversation by preventing confusion as to the association of certainalternate names and respective participants and by preventing repetitiveexchange of messages to identify who is referred to by what name,resulting in reduced and more efficient use of network traffics. Certainembodiments of the present invention may be implemented as an add-on orplug-in features of conventional messenger applications such that morefocused and efficient cognitive entity reference recognition andprocessing would be available than in messenger applications withintegrated entity reference recognition functionalities.

FIGS. 4-6 depict various aspects of computing, including a computersystem and cloud computing, in accordance with one or more aspects setforth herein.

It is understood in advance that although this disclosure includes adetailed description on cloud computing, implementation of the teachingsrecited herein are not limited to a cloud computing environment. Rather,embodiments of the present invention are capable of being implemented inconjunction with any other type of computing environment now known orlater developed.

Cloud computing is a model of service delivery for enabling convenient,on-demand network access to a shared pool of configurable computingresources (e.g. networks, network bandwidth, servers, processing,memory, storage, applications, virtual machines, and services) that canbe rapidly provisioned and released with minimal management effort orinteraction with a provider of the service. This cloud model may includeat least five characteristics, at least three service models, and atleast four deployment models.

Characteristics are as follows:

On-demand self-service: a cloud consumer can unilaterally provisioncomputing capabilities, such as server time and network storage, asneeded automatically without requiring human interaction with theservice's provider.

Broad network access: capabilities are available over a network andaccessed through standard mechanisms that promote use by heterogeneousthin or thick client platforms (e.g., mobile phones, laptops, and PDAs).

Resource pooling: the provider's computing resources are pooled to servemultiple consumers using a multi-tenant model, with different physicaland virtual resources dynamically assigned and reassigned according todemand. There is a sense of location independence in that the consumergenerally has no control or knowledge over the exact location of theprovided resources but may be able to specify location at a higher levelof abstraction (e.g., country, state, or datacenter).

Rapid elasticity: capabilities can be rapidly and elasticallyprovisioned, in some cases automatically, to quickly scale out andrapidly released to quickly scale in. To the consumer, the capabilitiesavailable for provisioning often appear to be unlimited and can bepurchased in any quantity at any time.

Measured service: cloud systems automatically control and optimizeresource use by leveraging a metering capability at some level ofabstraction appropriate to the type of service (e.g., storage,processing, bandwidth, and active user accounts). Resource usage can bemonitored, controlled, and reported providing transparency for both theprovider and consumer of the utilized service.

Service Models are as follows:

Software as a Service (SaaS): the capability provided to the consumer isto use the provider's applications running on a cloud infrastructure.The applications are accessible from various client devices through athin client interface such as a web browser (e.g., web-based e-mail).The consumer does not manage or control the underlying cloudinfrastructure including network, servers, operating systems, storage,or even individual application capabilities, with the possible exceptionof limited user-specific application configuration settings.

Platform as a Service (PaaS): the capability provided to the consumer isto deploy onto the cloud infrastructure consumer-created or acquiredapplications created using programming languages and tools supported bythe provider. The consumer does not manage or control the underlyingcloud infrastructure including networks, servers, operating systems, orstorage, but has control over the deployed applications and possiblyapplication hosting environment configurations.

Infrastructure as a Service (IaaS): the capability provided to theconsumer is to provision processing, storage, networks, and otherfundamental computing resources where the consumer is able to deploy andrun arbitrary software, which can include operating systems andapplications. The consumer does not manage or control the underlyingcloud infrastructure but has control over operating systems, storage,deployed applications, and possibly limited control of select networkingcomponents (e.g., host firewalls).

Deployment Models are as follows:

Private cloud: the cloud infrastructure is operated solely for anorganization. It may be managed by the organization or a third party andmay exist on-premises or off-premises.

Community cloud: the cloud infrastructure is shared by severalorganizations and supports a specific community that has shared concerns(e.g., mission, security requirements, policy, and complianceconsiderations). It may be managed by the organizations or a third partyand may exist on-premises or off-premises.

Public cloud: the cloud infrastructure is made available to the generalpublic or a large industry group and is owned by an organization sellingcloud services.

Hybrid cloud: the cloud infrastructure is a composition of two or moreclouds (private, community, or public) that remain unique entities butare bound together by standardized or proprietary technology thatenables data and application portability (e.g., cloud bursting forload-balancing between clouds).

A cloud computing environment is service oriented with a focus onstatelessness, low coupling, modularity, and semantic interoperability.At the heart of cloud computing is an infrastructure comprising anetwork of interconnected nodes.

Referring now to FIG. 4, a schematic of an example of a computersystem/cloud computing node is shown. Cloud computing node 10 is onlyone example of a suitable cloud computing node and is not intended tosuggest any limitation as to the scope of use or functionality ofembodiments of the invention described herein. Regardless, cloudcomputing node 10 is capable of being implemented and/or performing anyof the functionality set forth hereinabove.

In cloud computing node 10 there is a computer system 12, which isoperational with numerous other general purpose or special purposecomputing system environments or configurations. Examples of well-knowncomputing systems, environments, and/or configurations that may besuitable for use with computer system 12 include, but are not limitedto, personal computer systems, server computer systems, thin clients,thick clients, hand-held or laptop devices, multiprocessor systems,microprocessor-based systems, set top boxes, programmable consumerelectronics, network PCs, minicomputer systems, mainframe computersystems, and distributed cloud computing environments that include anyof the above systems or devices, and the like.

The componentsof computer system 12 may include, but are not limited to, one or moreprocessors 16, a system memory 28, and a bus 18 that couples varioussystem components including system memory 28 to processor 16.

Bus 18 represents one or more of any of several types of bus structures,including a memory bus or memory controller, a peripheral bus, anaccelerated graphics port, and a processor or local bus using any of avariety of bus architectures. By way of example, and not limitation,such architectures include Industry Standard Architecture (ISA) bus,Micro Channel Architecture (MCA) bus, Enhanced ISA (EISA) bus, VideoElectronics Standards Association (VESA) local bus, and PeripheralComponent Interconnects (PCI) bus.

Computer system 12 typically includes a variety of computer systemreadable media. Such media may be any available media that is accessibleby computer system 12, and it includes both volatile and non-volatilemedia, removable and non-removable media.

System memory 28 can include computer system readable media in the formof volatile memory, such as random access memory (RAM) 30 and/or cachememory 32. Computer system 12 may further include otherremovable/non-removable, volatile/non-volatile computer system storagemedia. By way of example only, storage system 34 can be provided forreading from and writing to a non-removable, non-volatile magnetic media(not shown and typically called a “hard drive”). Although not shown, amagnetic disk drive for reading from and writing to a removable,non-volatile magnetic disk (e.g., a “floppy disk”), and an optical diskdrive for reading from or writing to a removable, non-volatile opticaldisk such as a CD-ROM, DVD-ROM or other optical media can be provided.In such instances, each can be connected to bus 18 by one or more datamedia interfaces. As will be further depicted and described below,memory 28 may include at least one program product having a set (e.g.,at least one) of program processes that are configured to carry out thefunctions of embodiments of the invention.

One or more program 40, having a set (at least one) of program processes42, may be stored in memory 28 by way of example, and not limitation, aswell as an operating system, one or more application programs, otherprogram processes, and program data. Each of the operating system, oneor more application programs, other program processes, and program dataor some combination thereof, may include an implementation of thecognitive entity reference recognition engine 120 including thecognitive entity reference listing process 170 of FIG. 1. Programprocesses 42, as in the cognitive entity reference recognition engine120 generally carry out the functions and/or methodologies ofembodiments of the invention as described herein.
